Abstract
Abstract This disclosure relates to an adhesive composition for use in the manufacture of corrugated board and its preparation. The adhesive is prepared by using a thin boiling or modified waxy variety starch of fluidity of 25 or greater as a component in the gelatinized carrier portion of the adhesive. This produces a high solids carrier which results in a final adhesive of good stability whose use enables corrugated board to be produced at faster than normal rates. This adhesive is particularly useful to increase production rates of heavy weight and multiwall board.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A CORRUGATING ADHESIVE SUITABLE FOR MAKING HEAVY WEIGHT AND MULTIWALL BOARD AT FASTER THAN NORMAL RATES COMPRISING: A. 3 TO 12% GELATINIZED STARCH SOLIDS OF WHICH 25 TO 100% IS WAAXY STARCH MODIFIED TO INCREASE THE FLUIDITY THEREOF TO THE RANGE OF 25 TO ABOUT 90 MLLS. MEASURED AT 25*C., B. 10 TO 35% RAW STARCH SOLIDS, C. 0.1 TO 1.0% NAOH, AND D. 60 TO 86.9% WATER, WATER, SAID PERCENT BEING BY WEIGHT BASED ON THE FINAL ADHESIVE MIX THE AMOUNT OF GELATINIZED STARCH SOLIDS BEING SUCH AS TO PROVIDE AN INCREASED AMOUNT OF COOKED STARCH SOLIDS AS COMPARED WITH CONVENTIONAL CORRUGATING ADHESIVES, THE VISCOSITY OF SAID ADHESIVE BEING 16 TO 120 SECONDS ON THE BRASS CUP AT 105*F., AND THE WAXY STARCH BEING MODIFIED TO ALLOW SAID INCREASED AMOUNT OF COOKED SOLIDS WHILE RETAINING THE VISOCSITY OF THE ADHESIVE.
